SECURING MEANS FOR BOLTS.

Application filed January 10, 1917.

To all whom t may concern:

Be it known that I, GEORGE RUDOLPH HoHoRs'r, a citizen of the United States, residing at New York, in the county of Queens and State of New York, haveinvented new Aand useful Improvements in Securing Means for Bolts, fication.

My invention relates to improvements in securingmeans for axles, shafts, bolts, and the like, and more particularly to means for preventing rotation and longitudinal or end wise movement of the latter.

The object of my invention is to provide an extremely simple, cheap and efficient securing means to take the placeand perfoim the functions of the usual bolt-head, nut, cotter pin, and key or feather.

A further object is the provision of a removable and positive securing means of the character described that will, when fitted, present a perfectly smooth outer surface free from projecting nuts and bolt-heads.

iii/'ith the foregoing and other objects in View my improvements consist, broadly speaking, in the combination with a shaft or bolt having a transverse orifice, of a secuing pin inserted in the orifice and forced into diverging or oblique channels provided in the housing or shaft support.

Before describing my improvements speof which the following is a specicifically I wish it expressly understood that while I have shown the device in connection with a metal block, I do not limit myself to this single application of the invention, it being obvious that it may be used in connection with many other mechanisms without departing from the s irit or scope of the invention as defined in the appended claims wherein I do not limit myself as to size, proportions, or material employed.

In the drawings which accompany this application and constitute a part thereof, Figure 1 is a side View of a form of block with my improvement applied.

Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged view illustrating the securing pin inserted through the shaft or bolt and in a position ready to be driven or forced home into the diverging or oblique channels of the shaft support.

Fig. 4 is a View similar to Fig. 3 in which all the parts are shown in their relative positions after having been driven home and the protruding end of the'shaft or boltl fmished off, leaving only sufficient metal to Specication of Letters Patent.

prevent the pin from being ripped out of the head of the shaft.

Referring more specifically to the draw ingsin which like characters of reference are used to indicate like parts in the several views, the numeral l designates a shaft or bolt having near one end a transverse hole 2 in which is inserted a securing pin 3, while 4 indicates diverging or oblique channels which extend through the housing or shaft supporting means 5 and communicate with a recess 9 in the outer face of the housing.

rIhe parts 6, 7, and 8 are the ordinary ele` ments of a standard block that require no detailed description, not being pertinent to the present invention.

It is to be understood that the improvement may not only be used in connection with fixed shafts but also with shafts that require periodical or occasional removal, as the securing pin, being of medium steel (or any other material I may elect), will have suiiicient pliability to allow it to release the shaft when suiiicient force is properly applied. The size of the securing pin will of course depend upon the purpose for which it is used and the amount of torque and end thrust to which the shaft may be subjected.

Having described my invention, its construction and advantages, I claim as new and desire to secure by Letters Patent of the United States l. In a device of the character described, the combination of a shaft, a support for the shaft provided with a bearing to receive the shaft and with oblique or diverging channels oppositely disposed about said bearing, and a securing pin engaging said shaft and said channels.

2. In a device of the character described, the combination of a shaft having a transverse aperture therethrough, a support for the shaft provided with a bearingto receive the shaftV and oblique or diverging channels oppositely disposed about said bearing, and a distortable securing pin inserted in said aperture and having its opposite ends engaging said channels.

3. In a device of the character described, the combination of a shaft, a support for the shaft provided with a bearing to receive the shaft and with a recess in the face thereof and with diverging or oblique channels oppositely disposed about said bearing and a securing pin engaging said shaft, adapted to yield and irc,

he received in said recess, and its opposite ends forced into said channels.

L n a device of the character described, the combination of a shaft having u transverse aperture therethrough, :i support for the shaft provided with a hearing to receive the shaft and a recess in the face thereof1 and with diverging or oblique channels oppositely disposed about said bearing and at distortable securing pin inserted in said Aaperture and adapted to he received in said recess and its opposite ends Jforced into said channels.

In testimony whereof I, GEORGE RUDOLPH HoHoRsT, have signed my name to this speci- 15 cation, in the presence of two subscribing Witnesses, this fourth day of January, 1917.
